nuclear reactor - an apparatus in which nuclear fission may be initiated, maintained, and controlled to produce energy, conduct research, or produce fissile material for nuclear explosives.
Nuclear Reactors and Support Facilities: Uranium mills, commercial power reactors, fuel reprocessing plants, and uranium enrichment facilities.
N nuclear reactor
Definition (english only)
Device which creates heat and energy by starting and controlling atomic fission.
In a nuclear reactor, fuel rods full of uranium pellets are placed in water.
Inside the fuel rods, uranium atoms split, releasing energy.
This energy heats water, creating steam.
Waste generated in core fuel of a nuclear reactor, found at nuclear reactors or by nuclear fuel reprocessing; is a serious threat to anyone who comes near the waste without shielding. (See low-level radioactive waste.) ...
General term for materials used in nuclear reactors to reduce the energy (speed) of Fast Neutrons to that of Thermal (slow) Neutrons . The thermal neutrons are then able to interact and Fission with U-235.

Wastes less hazardous than most of those associated with a nuclear reactor; generated by hospitals, research laboratories, and certain industries.
However, nuclear reactors generate less than one-millionth the toxic waste (measured by net biological effect) per watt, when wastes of both power generation facilities are properly handled.
High-Level Radioactive Waste (HLW): Waste generated in core fuel of a nuclear reactor, found at nuclear reactors or by nuclear fuel reprocessing; is a serious threat to anyone who comes near the waste without shielding.
Background: The Chernobyl Nuclear Power Station included four nuclear reactors, each capable of producing one gigawatt of electric power. At the time of the accident, the four reactors produced about 10 percent of the electricity used in Ukraine.
Low-Level Radioactive Waste (LLRW): Wastes less hazardous than most of those associated with a nuclear reactor; generated by hospitals, research laboratories, and certain industries.
uranium A type of atom used to fuel nuclear reactors due to its ability to undergo fission with a free neutron creating a nuclear chain reaction and resulting in heat.
It is used in nuclear reactors, radio and television tubes, fluorescent tubes and powders. It is discharged by machine shops, ceramic and propellant plants, and foundries. In the environment, it ultimately accumulates in sediments.
Cooling water: Water used for cooling purposes, such as of condensers and nuclear reactors.
Cooling water blowdown: Procedure used to reduce total dissolved solids by removing a portion of poor-quality recirculating water ...
Radioactive Waste
Any waste that emits energy as rays, waves, or streams of energetic particles. Radioactive materials are often mixed with hazardous waste, usually from nuclear reactors, research institutions, or hospitals.
Nuclear reprocessing is the recovery of unused plutonium or uranium from irradiated fuel that has been used up in nuclear reactors- the systems used to carry out nuclear fission.
power plants, which is why some consider nuclear power cleaner than power from fossil fuels. However, nuclear power can also pose problems such as disposal of radioactive waste. Uranium and other radioactive elements are used to feed nuclear reactors.
compounds so that the structure or chemical activity can be determined. Also used in nuclear weapons research and construction. Small amounts of tritium occur naturally, and some exists as a by-product of previous nuclear testing and nuclear reactor ...
